Benefits of technology

[0009]It is an object of the present invention to provide an automatic document feeder having small volume.
[0010]Another object of the present invention provides an automatic document feeder to minimize the possibility of damaging the document.

Problems solved by technology

However, the process of manually turning over the document is troublesome.
Although the conventional automatic document feeder 1 has a function of stopping the document D from entering the internal portion thereof when the automatic document feeder 1 is disabled, there are still has two problems.

Embodiment Construction

[0031]For obviating the drawbacks encountered from the prior art, the present invention provides an automatic document feeder. FIG. 4 is a schematic side view illustrating an automatic document feeder in a standby mode according to an embodiment of the present invention. The automatic document feeder 2 comprises an upper cover 20, a pick-up module 21, a transfer channel 22, an ejecting roller 23, an input tray 24, an ejecting tray 25, a stopper module 26, a transfer roller 27 and a stopping indentation 28. Plural documents D′ to be scanned are placed on the input tray 24. The scanned documents D′ are supported on the ejecting tray 25. The pick-up module 21 is used for successively feeding the documents D′ that are placed on the input tray 24 into the internal portion of the automatic document feeder 2. After the documents D′ are fed into the internal portion of the automatic document feeder 2, the documents D′ are transported through the transfer channel 22. The transfer roller 27 i...

Abstract

An automatic document feeder includes an upper cover, an input tray for placing plural documents, a pick-up module and a stopper module. A guide plate is disposed on the upper cover. The guide plate has a confining aperture. The confining aperture includes a fixing region and a releasing region. The stopper module has a stopping slice inserted into the confining aperture. When the automatic document feeder is enabled and the pick-up module is swung to be close to the input tray, the stopper module is moved from the fixing region of the confining aperture in response to the swinging action of the pick-up module. As such, the stopper module is released and the document is allowed to be fed into the internal portion of the automatic document feeder.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an automatic document feeder, and more particularly to an automatic document feeder with a stopper module.BACKGROUND OF THE INVENTION[0002]With increasing development of scientific technologies, the method for storing documents is changed from filing of paper documents to storage of documents' electronic files. A scanning apparatus is a device for scanning the contents of paper documents into electronic files, which are then stored, processed or spread.[0003]In the early stage, the scanning apparatus can scan one side of the document. For scanning both sides of the document, the document should be manually turned over after one side of the document has been scanned in order to sequentially scan the other side of the document. However, the process of manually turning over the document is troublesome. Recently, a duplex scanning apparatus has been developed for automatically performing a duplex scanning operation to scan bot...
